Over 20 people were injured in the attack that took place in the Mastung district of Baluchistan province. Officials said that some of the injured victims were in critical condition and that the death toll could rise. Initial reports said the bomb had been detonated by a remote control, but a government official said it was a suicide attack. No group has claimed responsibility for the incident, says the BBC.
